### ⭐ Absolutely terrible. Complete waste of time and money
*by A***R on 19 October 2024*

Item was delivered and put together. The motion lasted around 15 seconds before stopping. After about using it 6 times it became completely tangled up and couldn't be untangled. I had no option but to throw it away. Complete waste of time and money.
